Re: Bobs Outboard Exhaust Housing ??
Sounds like you have already removed tha can I think? Ta use tha Bob's ya hafta drill tha vertical part of tha mid. If you go ta drillin' holes in tha vertical part of the downhousing ya risk weakening tha thing especially if your surfacing gearcases and props. That puts a very big torque load on tha downhousing (more so on tha bottom). Has a possibility of crackin or breakin'. Not sayin' it will or won't but its something ta consider. Seen some break and some that haven't. You could just drill tha 10 holes on tha horizontal surface at tha base like tha Merc High Perf. Bass mid. It sounds off pretty good
Plus tha "cops" can't say its not "production exhaust". They get uppitty 'round here sometimes

Sounds like ya got an 18' Action. If you haven't already ya might consider a blow-out ring on tha cle if its stock............
